Shoe sleeved structure

ABSTRACT

The utility model discloses a shoe with a shell structure. The shoe with the shell structure is comprised of two main components, namely, a shoe shell and a shoe body. The shoe body is comprised of an upper, a bottom and a wearing opening, while the shoe shell is comprised of a vamp upper, a sole, a wearing opening and a buckle assembly. 
     The shell vamp upper and the sole form an inner space and the shoe body is just suitable for the inner space of the shoe shell. Therefore, a wearer can wear the shoe body and then put on the shoe shell. 
     If the shoe shell or the shoe body is damaged after being used for a long time, only the damaged assembly is replaced. The other good assembly can be continuously used, saving material and protecting the environment. 
     Furthermore, different designs of the shoe shell and shoe body can be produced, and the combination of shoe shell and shoe body can be exchanged and/or interchanged for the purpose of function, style or replacement.

TECHNICAL FIELD

This utility model relates to the technical field of footwear; separate uppers and outsole with a changeable shoe shell to house them.

BACKGROUND

The footwear unit (1) provides the characteristics of footwear with regards to traction, protection, support and durability but allows use with a variety of uppers (2). As 1 or 2 wears out, the still functional item (1 or 2) can still be used with a replacement of 1 or 2. This allows for maximum use of the individual components—1 (the shoe outsole, midsole, shell vamp upper) and 2 (the shoe body upper).

The existing sneakers (reference 60) also have the above mentioned characteristics, but the producing method is different. The uppers, outsoles and linings (62, 63) and other components are glued together or combined with threads, providing no chance to repair or replace one of these separately. In case one of those components, either the upper, lining of sole is damaged or broken, the whole shoe has to be replaced.

Utility Model Content

The main utility purpose is to be able to use different shoe uppers with the outsole/shell body and give the user the option to replace either component for whatever purpose they may desire. It is thus more economical and ecological.

The shoe shell component (1) has the following construction details:

The shoe shell component (1) is comprised of an outsole, midsole and molded vamp upper designed to fit the footwear upper (2) and create a secure attachment system between 1 & 2;

The shoe body upper (2) with a closed bottom surface is designed to fit into the interior surface of the shoe shell (1);

The vamp upper can be with vents;

Shoe shell can be made in one piece;

The shoe shell vamp uppers (1) can be sewn, bonded or welded together;

Upper materials (1) may be comprised of fabrics, synthetics, leathers or plastics

The shoe body uppers can be sewn, bonded (with adhesive) or ultrasonically welded together. The outsole and shell unit can be sewn, bonded (with adhesive) or ultrasonically welded together;

A tab can be sewn on the shoe collar;

The shoe material can be fabrics, synthetics or leather materials;

The upper and bottom of the shoe body can be sewn, bonded (with adhesive) or ultrasonically welded together.

Therefore, this utility model has following advantages:

1, the shoe body and shoe shell can be interchanged or replaced separately. It is thus more economical and ecological.

2, this utility model can be used as outdoor shoe. On the other hand, the shoe body upper (2) can be worn as a slipper indoors. The uppers can be disassembled from the outsole/shell (2) for this purpose.

3, this utility model is designed and engineered for diversity of style and function within the same product.
